"The murderer should be more than this account, you check the social accounts of this platform near this IP address, and check them one by one."

It is no longer the era of Bai Longyin, and after 20 years, the technology has leaped a lot, and Zhang Jiahua has been involved in the research and development of some technologies in the special task force, so it is easier to verify.

Due to the high accuracy, the locked IP range is relatively small, and it will be found out after 20 minutes.

"Found it, in this building." After Zhang Jiahua finished speaking, he put out the real map through the computer and enlarged the building.

Bai Yaqing took a look, this building has twenty floors, how can I check this? It's useless to check for a day and a night!

"This ...... Let's not talk about twenty floors......" Bai Yaqing exclaimed.

"Wrong, it's not twenty floors, it's twenty-nine floors to be exact, it's an independent residential building." Zhang Jiahua added.

"Hey, it's not a matter of how many floors there are, even if it's only twenty floors, it will take a long time to investigate!"

"But that IP address can only be found in its location, and these twenty-nine layers are superimposed, and the address is unchanged." Zhang Jiahua said.

To put it bluntly, if your home is on the 10th floor, your neighbor is on the 9th floor, and you live in Building 1, but the IP addresses of the two of you are Building 1,......

"You can look up the residents of that building." Zhang Zijun said.

Now that it has been determined that the murderer's sex is a woman, it is enough to find out the female householder. Whether it is a tenant who rents or buys, it can be checked.

"Quick troubleshooting."

On the big screen, the image of the building was locked, and through the system technology scanning, there were three households on each floor except the first floor...... Of the 84 households, 36 are registered as females.

"The rest of the households may have women living in the family." Zhang Zijun said.

"Let's check the thirty-six heads of households first, and then let's rest for a while." Bai Yaqing looked at the time and said.

As soon as the words fell, Bai Yaqing turned his head and said to Shasha: "Order a takeout, I will invite everyone to eat, and only when you are full will you have the brains to think about the case." ”

"Okay! Thank you, Team Leader! ”

The speed of this takeaway was a little faster than the speed at which they checked the information, and soon the takeaway they ordered came, it was some barbecue and a big pizza.

Bai Yaqing stood up and slapped her palms twice, "Okay, let's eat something first!" Take a break! ”

"Wow, that's great!"

"Thank you, team leader!" Everyone thanked Bai Yaqing in unison.

After eating, they took a little rest, and the results of the investigation over there had already come out.

According to the system, 27 of the 36 female heads of households are married, and the remaining nine are single.

"This doesn't mean anything, married people can also kill, print out their addresses, check it tomorrow, now everyone go back first."

Bai Yaqing looked at the time, it was more than eleven o'clock, and it was not early, so let them go back and rest. Only when you have a good rest can you do a better job and investigate cases.

……………………

Early the next morning, the office of the serious crime group was empty, and everyone had already gone out to investigate before they came to report to work.

Bai Yaqing, the developer of the residential building, was also contacted and directly contacted the person in charge of management.

With the cooperation of the person in charge, the progress of the investigation is also much faster......
